Abstract
Disclosed is a reducing nipple of a plastic pipe. A small reducing pipe section is radially fixed into a large reducing pipe section in a suspended manner, and a gap between one end of the small reducing pipe section and the inner circumference of the large reducing pipe section is sealed by a ring surface. Therefore, the shortcomings of a reducing nipple in the prior art are overcome, arbitrary pipe diameters can be changed once, reducing connection strength is high, a reducing pipe does not need to be lengthened, leakage is not easily caused after connection, and the workload of maintenance in the future is greatly decreased.
Description
Technical field
The utility model is the improvement to the plastic tube reducer union, relates in particular to a kind of not only reducing wide ranges, and two plastic tubes of arbitrary size can realize that a reducing connects, and reducer pipe is short, cost is low, and join strength is high, the plastic tube reducer union that is difficult for producing seepage.
Background technique
In the connection procedure of plastic piping, for example the water treatment pipeline connects, and usually needs to change the caliber that connects plastic tube, realizes that namely big or small reducing connects.Prior art size reducing reducing connects, usually adopt and make reducing by the plastics pipeline section socket that number reduces and connect, if need the variation of reducing large, then need the plastics pipeline section of a plurality of different tube diameters to be socketed one by one, cause reducer union many, for example caliber is 20mm by 63mm, in the middle of needing by number reducing 5 of transition connecting pipes, simultaneously also increased the reducing link cost, a plurality of joints produce seepage easily, increase maintenance cost.
Chinese patent CN2648231 plastic pipeline reducing connecting piece adopts a taper reducer pipe, and it is to being set to a plurality of different-diameter steps, the middle reducing connecting piece that a plurality of transition reducers are arranged of formation at the taper outside journal axle.This type conical bench reducing link, the one, make comparatively trouble, and owing to there are a plurality of middle transition reducer length relatively long, increased reducing link cost; The 2nd, because the different-diameter section only is a ring, the diameter-varying ring insertion connects weak point, and is firm not, the leakage maintaining trouble occurs, so can not be used for the unsettled reducing connection of pipeline, usually need fix by extra increasing in the reducing joint, to improve join strength.
Chinese patent CN2921524 inner screw thread reducing joint, by a cylindric plastic tube body, a port radially closes up and forms reducing socket less than the plastic tube body internal diameter, and the other end is processed with internal thread.This reducer union is not only made more complicated, need machining screw, and reducing socket width is narrower, affects equally the reducing join strength, easier generation seepage.
Chinese patent CN1164625 plastic pipeline reducing connecting piece is to be provided with outside reducing socket at bassoon one end.Although this structure has increased the reducer pipe intubating length, be conducive to improve the reducing join strength, must lengthen reducer pipe length, cause cost to increase; Secondly, may increase by one in its periphery and enlarge ring for strengthening evagination reducer pipe intensity, so that the increase of reducer pipe diameter is very large, impact is in the installation at some position.
Although above-mentioned prior art can realize reducing of reducing, all come with some shortcomings, for example make complexity, reducer pipe length is long, and the short join strength of reducing linkage section is low, long rear easily generation seepage of time, maintenance load is large especially in the future.Above-mentioned deficiency still has is worth improved place.
Summary of the invention
The utility model purpose is to overcome above-mentioned the deficiencies in the prior art, and a kind of not only reducing wide ranges is provided, and two plastic tubes of arbitrary size can realize that a reducing connects, and reducer pipe is short, cost is low, and join strength is high, the plastic tube reducer union that is difficult for producing seepage.
The utility model purpose realizes, the main improvement is to be fixed in the bassoon the reducing tubule is built-in, reducer pipe one end and outer tube diameter spacer ring face closure, thus overcome the deficiencies in the prior art, realization the utility model purpose.Specifically, the plastic tube reducer union, comprise the large pipeline section of reducing of socket connection and the little pipeline section of reducing of socket connection, it is characterized in that the little pipeline section of reducing is radially unsettled is fixed in the large pipeline section of reducing, and wherein there is the anchor ring sealing in little pipeline section one end of reducing and the large pipeline section internal diameter of reducing gap.
The large tubule size of reducer union is determined, by common socket connection mode, for example determines the large pipeline section external diameter of reducing according to connecting large bore, and reducing tubule external diameter is determined reducing tubule section internal diameter as required.
There is the anchor ring sealing in little pipeline section one end of reducing and the large pipeline section internal diameter of reducing gap, mainly cut off bassoon liquid by the short stream in internal and external casing gap, by closing gap bassoon liquid are flowed by the reducing tubule.Anchor ring sealing can be planar surface encloses, but wherein a kind ofly preferably is conical ring face (umbrella shape) by liquid flow direction, can reduce the variable diameter guide flow resistance like this.
The little pipeline section of reducing is radially unsettled to be fixed in the large pipeline section of reducing, a kind ofly preferably adopts alternate radial spoke, and this mode can be saved the reducer union material.
For reasonable coordination with material amount and join strength, the reducer pipe segment length, preferably connect about half of plastics caliber, connecting reducing pipe diameter 16mm for example, then the little length of pipe section of reducing is comparatively suitable about with 8mm, and large pipeline section is same so to be determined, but the technician is clear, obviously this numerical value is not exact value on the mathematics, and just reflects a kind of relative quantity concept.
Make for simplifying, inside and outside unsettled sheathed big or small pipeline section a kind ofly better is concentric setting, and off-centre neither as required certainly.
Connect after making things convenient for gluing, large pipeline section one end of a kind of better reducing has the polygon ring of evagination, rotation after being used for pegging graft, and to guarantee join strength, this ring also can be used as and connects socket joint not-go-end back-up ring simultaneously.
In addition, can also be provided with convex at the little pipeline section one end internal diameter side face of reducing and end slotting ring, join strength is guaranteed in position when being inserted into when guaranteeing to connect.Better be to make convex end slotting ring to be relative position with the large polygon ring of pipeline section evagination, be convenient to linearly connect.
The reducer union of the utility model plastic tube, with respect to prior art, owing to adopt the radially unsettled large pipeline section inner structure of reducing that is fixed in of the little pipeline section of reducing, thereby overcome the deficiency of prior art reducer union, not only can realize a reducing of arbitrary size caliber, and the reducing join strength is high, and need not increases reducer pipe length, be difficult for after connecting producing seepage, greatly reduced in the future maintenance load.
Optimize exemplary embodiment below in conjunction with one; model utility essence is further understood in exemplary illustration and help; but embodiment's detail only is for model utility is described; do not represent the lower whole technological schemes of model utility design; therefore should not be construed as the total technological scheme of model utility is limited; some are In the view of the technician; the unsubstantiality that does not depart from the model utility design increases and/or change; for example change or replace so that technical characteristics with same or similar technique effect is simple, all truely use novel protected scope.
